Bulbs | 1–3, increase bulbs absent or ± equaling parent bulbs, never appearing as basal cluster, not clustered on stout primary rhizome, ovoid to globose, 1–1.8 × 1–1.7 cm; outer coats enclosing 1 or more bulbs, gray-brown to brown, prominently cellular-reticulate, membranous, cells arranged in ± vertical rows, forming irregular herringbone pattern, transversely elongate, V-shaped, without fibers; inner coats white, cells obscure, ± transversely elongate, contorted. |
1–5+, not clustered on stout primary rhizome, rhizomes absent, renewal bulbs formed within coats of parent bulb, ovoid to ± globose, 1–2 × 0.7–2 cm; outer coats enclosing 1 or more bulbs, gray to grayish brown, membranous, lacking cellular reticulation or cells arranged in only 2–3 rows distal to roots, ± quadrate, without fibers; inner coats white or pinkish, cells obscure, ± quadrate. |
Leaves | persistent, withering from tip by anthesis, 2–3, basally sheathing, sheaths not extending much above soil surface; blade solid, flat, broadly channeled, carinate, 20–75 cm × 5–10 mm, margins entire. |
